SHEET-PILING ATTACHMENT FOR PRINTING-PRESSES.

SPECIFICATION forming part of Letters Patent No. 372,410, dated November1, 1887.

Application filed February 16, 1885. Rerewed September 14, 1887. SerialNo. 249,688. (No model.)

To all whom it may concern.-

Be it known that I, CARL HAFFNER, of Brooklyn, in the county of Kingsand State of New York, have invented certain new and useful Improvementsin Sheet Piling Attachments forPrinting-Presses,of which the followingis a specification.

This invention has reference to an improved sheet-piling attachment forthe fly-table of printing-presses,whereby the sheets delivered bytthefly are piled up regularly without requiring the attendance of aiiy-boy.

The invention consists of a sheet-piling attachment for the fly'tablesof printing-presses, which is composed of a wing shaped upper part andan openframed lower weighted part, said attachment being hinged to theedge of the fiy-table, as will appear more fully hereinafter and finallybe pointed out in the claim.

In the accompanying drawings, Figure 1 represents a side elevation ofthe rear end ofa printing-press. showing my improved sheetpilingattachment arranged at the fly-table of the press. Figs. 2 and 3 showside and end elevations of my improved piling attachment, drawn onalarger scale. Fig. 4 is an end view of the fly-table with my improvedattachment.

Similar letters of reference indicate corre sponding parts.

A in the drawings represents the fly-table of a printing-press, to therear edge of which is applied the sheet'piling attachment B, that ismade of a wing-shaped upper part, b, of thin sheet metahthat extendsabove the fly-table A, and of a lower weighted part, (Z. The wing shapedpart bis hinged to the edge of the flytable or below the same, the lowerweighted part being formed of a wire frame, as shown in Figs. 2 and 3,that is provided with eyes d d for the pintle e of the attachment.

When the front and side gages, f, have been placed in proper position onthe fly-table and the printing-press is started, the fly delivers thesheets onto the fly-table, which are then regularly set u p by thepiling attachment. The draft exerted by the air on the upper wing shapedend of the piling attachment throws the same in backward directionagainst the action of its weight, while thelatter returns thewing-shaped upper part and moves thereby the sheet forward by theoscillating motions imparted to the attachment. As one sheet afteranother is delivered on the fly-table the piling attachment arrangesthem in connection with the gages in a reliable and uniform manner.

I do not claim the combination, with a receiving-table provided withgages and a By sheet-delivery, of an evener or straightening device hungat the outer edge of the table, capable of outward movement by theblasts of air produced by the fly and adapted in its return movement topush inward the newly-delivered sheet against the gages. Nor do I claimthe combination, with a receivingtable having gages and a fly, ofanevener or straightening device made heavier at its lower portion andhung to the outer edge of the table.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- A sheet-piling attachment for the fly-tables ofprinting-presses,composed ofawingshaped upper part and an open-framedweighted lower part, and a hinge for connecting the attachment to theedge of the table, substantially as set forth.

In testimony that I claim the foregoing as my invention 1 have signed myname in presence of two subscribing witnesses.

CARL H AFFNER.
